You can find 93 almost everywhere.

I'm surprised no one has pointed out that this is really a function of federal and state laws to meet pollution requirements. When the law says you can't have good gas then no one in that area is going to have good gas. Here is a partial list of cities to avoid. http://www.epa.gov/oms/regs/fuels/420b05013.pdf
That is just a very small list. I've seen a national map but couldn't quickly find it. Bottom line is, if you want 93 octane you usually just have to stop outside metropolitan areas. Never buy gas when you start getting close to a large city.

Is this the same BP that ignored it's employees concerns regarding safety.The same BP that ignored Higher tech safety devices that could have been used that caused loss of life for the sake of profit?You are refering to British Petroleum not some other BP.The same BP that around here that "erased"the "BP" lettering off it's signage. Your morallity IMO is at question my friend and I am glad I live in an area that sees through their 
and on a whole refuse to give such a business any partonage.They have their fuel today priced out at. 07$ less than all the oyher station around but they are buying off few takers including me. BP sucks

Oklahoma, almost non-existent. I have no idea why. 91 octane is about it. there are a couple of places in Oklahoma City and One in Tulsa I understand that you can get non-ethanol 93 and 100+ from the pump.

Citgo here in NC used to carry 100 octane and was labeled race gas. About $1 more than premium. Many Citgo's were taken over by Texaco. 93 octane is the normal premium here.

Some brands don't have a 10% mix of ethanol in premium fuels but it's in almost all 87 octane stuff. But it won't be long before ethanol in even higher percentages for all grades will be the norm.
I think that most all stations in Oregon has 92 octane gas for premium.
Back in the 60's I remember buying "Chevron Custom Supreme" for my 69 Road Runner on drag racing nights. $5 got me about 12 gallons and that was enough for the round trip to Puyallup Raceway and back and maybe a dozen passes.
Back then, I used to see Washington State Patrol cars (late 60's Plymouth Fury III's with 440's and 427 Impalas) filling up with Custom Supreme. Figured if it worked for them, it would work for me.

Anther station I filled up with 93 at was a Conoco in Cullman AL on Hwy 72 and another was at a Chevron in Lincoln, AL, I-20 and Hwy 77. I'm pretty sure I got 93 at a Exxon station on rte 302 in Olive Branch, MS.

Didn't I learn in high school chemistry that octane ratings are a function of altitude? 93 at sea level is the same as 91 at 5,000ft. ...or something like that... chime in all you chemistry professors...

93 Octane Gas
You would probably use up less space if the States that do not have 93 octane were listed.
Having resently returned from a trip to Pensacola to attend a Military reunion I had the oportunity to use the 93 octane gas available in some of the states I was passing through. Well fellow Corvette drivers I had no idea the change would be so noticeable especially during acceleration. The engine advances the timing when it senses the higher octane fuel and that increases the performance.
